"I am not great in that area and want some advice on it."
Your instructor should give you a method, and with discipline, you should improve your performance.
If your performance does not improve, it's either that you're not disciplined enough AND/OR that you don't understand what to do.
If you don't understand what to do you, have the method explained again by your instructor. If it's still not clear, you might want to hire another instructor, these things happen.
